IPC: H01L31/10
Filed: 1991-09-03
Abstract: PURPOSE:To shorten a diffusion process and to reduce the variation of diffusion and that of current gain hFE at the time of heat treatment in a phototransistor of base dual structure. CONSTITUTION:A high-concentration, deep P-type light-receiving part base diffusion layer 11 is previously formed around a region, where an emitter is expected to be formed.

Title: Liquid crystal display device
Inventor: YAMAMURA AKISHIGE
IPC: G09G3/18
Filed: 1986-09-20
Abstract: PURPOSE:To prevent the white level of a bright image plane from being absent and the black level of a dark image plane from being lost by providing a detecting circuit which detects the envelope of an AC driving signal and feedbacks a detection signal to a control terminal and an inversion prevention circuit which limits the lower-limit level of the detection signal and prevent the polarity of the AC driving signal from being inverted erroneously. CONSTITUTION:The detecting circuit 7 detects the envelope of an input signal and feedbacks the detection signal which varies in level in inverse proportion to the maximum amplitude of the input signal, i.e. P-P value to the bright control terminal of a setting circuit 2. The preventing circuit 8 limits the lower limit of the level of the detection signal by clamping a potential E2 so that the potential E3 of a control terminal 9' is higher than Ey. At this time, the AC driving signal of the three primary colors of a switching circuit 6 has the pedestal level on the side of a reference potential E0 all the time and the pedestal level is lowered as the image plane becomes darker based on the level of the detection signal and raised as the image plane becomes darker. Consequently, the white level of the bright image plane is prevented automatically from being absent and the black level of the dark image plane is prevented from being lost, thereby improving display performance.

Title: Desuperheating device
Inventor: MORIKAWA SHOJI
IPC: F22G5/12
Filed: 1989-08-31
Abstract: PURPOSE:To drastically improve the mechanical strength and reliability of a desuperheating device as a whole by providing a low-temperature fluid line with a bypass having a regulating means in a setup to supply a flow of minimum quantity to a spray nozzle by injecting low-temperature fluid through the bypass. CONSTITUTION:A low-temperature fluid line 15 is provided with a bypass 24 having a regulating means (regulating valve) 25. Besides a water injection- regulating valve 14, the bypass 24 is provided for the purpose of securing a quantitatively minimum flow and a regulating valve 25 as a means of effecting minute adjustments according to the load. Since the function does not involve ON/OFF control of the spray, the variation in the temperature difference is drastically reduced and hence thermal stress is decreased. Even when the water injection-regulating valve 14 closes and the supply of low-temperature fluid B to a spray nozzle 17 through the low-temperature fluid line 15 is shut off, the regulating means 25 in the bypass 24 opens to supply low-temperature fluid B through the bypass 24.

Title: Fuel injection device of engine
Inventor: YOSHIDA TAKEO
IPC: F02M67/12
Filed: 1990-08-24
Abstract: PURPOSE:To improve the engine performance by providing an orifice connected to the atmospheric side from an injection chamber so as to carry out an adequate amount of fuel injection to the injection chamber, in an engine which carries out the injections of a fuel injection valve and an air injection valve alternatively. CONSTITUTION:To a branch passage 35 extending from an air passage 27 to the outside, a plug 36 furnishing a minute diameter of orifice 37 is screwed up to mount and demount freely. An injection chamber 19 is connected to the inside of a suction pipe at the atmospheric side at the upper stream side from a throttle valve. After the mixture gas 38 in the injection chamber 19 is injected to a combustion chamber 13 through a nozzle valve 32, a certain amount of air 39 remains in the injection chamber 19, but the residual air 39 is returned to the suction pipe through the orifice 37. As a result, when the next injection is carried out from the fuel injection valve, a specific injection can be made regardless of the residual pressure. Although a part of the injection fuel and air is liable to go to the suction pipe through the orifice 37 when the fuel and the air injection valves carry out the injections, no influence is given to the whole injection amount, because the diameter of the orifice 37 is very small.

Title: Humidity sensor
Inventor: YOSHIDA TAKASHI
IPC: G01N27/12
Filed: 1990-08-24
Abstract: PURPOSE:To obtain a sensor of good response to the humidity by furnishing a moisture sensitive material whose electric resistance varies with the absorbed moisture between the electrodes on a base bard, a heater to pyrolyze the contaminants on the surface, and a heat conduction control means for the two members in between. CONSTITUTION:When a heater 7 is operated to raise the temp. up to the critical temp., a shape memory alloy 10 makes rapid thermal displacement and separates from a base board 1, so that the surface temp. of a moisture sensitive material 2 falls quickly. When the supply voltage is shut, the temp. of alloy 10 itself sinks slowly, and if it attains near the initial temp., displacement occurs abruptly to cause tight contacting with the base board 1 again. In this manner the heater 7 is isolated because of displacement of the alloy 10 when the temp. of the moisture sensitive material 2 is going to return to normal temp. after the heating cleaning process, so that influence of the surplus heat is reduced, and the sinking time to the normal temp. is shortened. This will enhance the response characteristic.
